This is the 2.0 release of the "unworked" enhancement patch for Lunar: Eternal Blue for the Sega CD which was originally released in 1995 by Working Designs.
This patch focuses on undoing the changes Working Designs made to the original Japanese game while keeping their English translation. Like with their other games, Working Designs made significant changes to the game balance. They also made some small edits to the graphics at Sega's request. All of those changes are reverted here so that it plays and looks just like the Japanese version. The original version of the translation also featured an all-uppercase font due to technical limitations; this has been replaced with an easier-to-read mixed-case font.
This 2.0 version of the patch fixes some bugs and improves the text in the original version of the patch.
The 1.0 patch contained these changes:
Magic Experience is no longer needed to save the game. This was one of Working Designs's most controversial changes and required players to choose between saving their game or improving their spells.
Text features a new mixed-case font and the script has been updated to use it.
All character and enemy stats are like they were in the Japanese version.
All pentagrams have been restored.
Plantella wears her original outfit.
A few shots of Lucia in the opening cutscene have been restored to the Japanese versions.
The shot of Luna in a flashback cutscene features the original brightness.
This 2.0 version of the patch keeps all of those changes while also making many improvements and bugfixes:
The intro cutscene no longer desyncs on original hardware or certain emulators.
Load times have been slightly improved.
Many improvements to the script, fixing miscapitalizations and places where text would run off the edge of a line. This includes both fixes to the original Working Designs script and bugs introduced in the 1.0 version of the patch.
The patch can now be applied straight to a BIN/CUE copy, making it easy to use and burn.
